True, when analyzing data measured by a continuous quantitative variable, the statistical tests of estimation and contrast frequently used are based on supposing that a random sample has been obtained from a probability distribution of normal type, but in many cases this assumption is not valid, in these cases we have two possible mechanisms: The data can be transformed in such a way that they follow a normal distribution or you can resort to parametric or non-parametric tests.

Thomas Jefferson was one of the many anti-federalists who held the belief that power should not be vested on a single person but on multiple people. He created and introduced the decimal-based currency system for the better exchange system for business or any transaction.
The type of money system that he designed and started was the coinage system or the use of the coin in any system of transaction. Thus, the correct answer is COIN.
Energy was lost due to work done by the ball pushing on the floor during the collision.
Answer:
Option B
Explanation:
As per Newton's third law of motion, every action has an equal and opposite reaction. So if an object is made to drop from height to reach the floor, then its kinetic energy when the object is moving will be transferred to the floor on hitting the floor. Thus, this loss of kinetic energy will lead to rebounding of ball to 90% of original fixed height and not to the same height. So the point the ball hits the floor, the kinetic energy of the ball will be utilized to push on the the floor such that the ball can rebound itself. Hence, it is stated that the loss of kinetic energy of the ball during collision is because it is lost due to work done by the ball pushing on the floor during the collision.
<span>True. Creativity and innovation are almost equal concepts because both are a source of new and creative ideas for designs, creations, thoughts, works of art and all kinds of projects that require creative thinking and constant innovation. They are not completely the same because creativity is creating in a different and particular way and innovation is the creation of novel works from new ideas not seen before. For this reason, they are almost the same.</span>
